[libcamera-devel] [PATCH] ipa: raspberrypi: Return controls::FrameDuration from the IPA

[Naushir Patuck]

Return controls::FrameDuration through the per-frame Request metadata. The
frame duration is obtained by either the value in DelayedControls, or
(preferably) the value parsed from the embedded data buffer.
